Sorry I just re-read your post and notice you asked if Alcidion's product is being trialed in any hospitals yet.
I can answer that one - There are already a number of paying customers (hospitals) using the Miya product here in Australia.
Although marketing is not really the same thing as product delivery/keeping up with demand - I have already asked Nathan about this previously.
The demand in the US will be incredibly large, the issue there will be keeping up with demand (something important to consider obviously whether a company has matured to be able to handle huge levels of demand)... When I asked Nathan about the approach he has for this, he said he is unable to disclose at this stage as it not yet publicly available. I look forward to hearing what his plans are - gauging by Nathan's incredible track record it will be something interesting no doubt! I would assume he is very well connected in the US considering his previous businesses.
I am going to guess it is not OEM avenue. I have a few thoughts in mind, but I am sure we will find out soon enough.
